HYDRAULIC DRAIN TILE COM- DRAIN-TILE-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 352,448, dated November 9, 1886.

'Application filed December 11, 1885. Serial No. 185,352. (No model.)

To all whom it may concern,.-

Beit known that I, ROBERT J. CARSON, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented a new and useful Drain- Tile-Making Machine, of which the following is a specification.

My invention relates to improvements in drain-tile-making machines in which the con- [0 crete or other material used is thorougly worked and packed into a shell provided, having a rotary motion and so constructed as to easily allow the tile to be removed from said shell when completed; and it consists in the improved construction and combination of parts, as will be hereinafter more particularly described and pointed out in the claims.

Figure 1 is a side elevation of the machine.

Fig. 2 is front elevation of the machine, or the side at which operator controls machine. Fig.

3 is a top view of machine. Figs. 4 and 5 show,

respectively,a plan and sectional view' of fiexible core; Fig. 6, detail views of packing-rod guides; and Fig. 7, detail arrangement for giving required rotary motion to core-protector Fig. 8, lever for starting receivingshell K and revolving table I downward.

Referring to the accompanying drawings,

in which the same letters of reference indicate,

3o corresponding parts in all the gurcs, A A represent the standards ofthe machine, each of which, together with the cross-pieces a a, are madeof one piece. These standards are secured to each other by means of additional cross-pieces, b b, upon the front and rear portion of the machine. Upon the front part of this frame a table, R, is movably secured by means of the vertical guideways ss, one upon each lside of the machine. Two counter- 4o weights, S S, are secured to the sides of the table by means of two ropes or Cords, which pass over pulleys b b. rlheforward part of this table is made round, so as to permit of easy access to the machinery, and it is also provided in its top with a hole or aperture. A revolving annular table, I, is secured upon the top of the table R by means of the flanged annular cover Il. A vertical rack-bar, E, is secured upon the front cross-pieces, b, at the 5o rear of the table, to the lower end of which is beneath when the machine is at rest.

secured the forwardly-projecting arm O1. A hollow flexible core, F, is secured to this arm by means of the rod St, and projects through. the holes in the tables R and I.

Secured to the topof the frame, by means of the forwardly-projecting bracket V, "is a coreprotector, Q, which extends down to the top of the table I when Said table is in its raised position. Around this protector is a hopper,

J, which is of the saine' length as the core-pro- 6o tector Q, and has its upper end made flaring to receive the concrete or other material out of which the tile is to be made. Secured to the bracket V, by means of the bolt m', and eX- tending down over the top ofthe protector Q,

by means of the arms u, is an annular guide, o', having notches t upon its'inner side. Fitting around the lower end of the hopper J, and resting upon the table I, is a shell, vK, which Ais slightly longer than the length of the tile to 7o be made.

Pivoted to the top of the frame is a series of levers,O, to the front ends of which are secured an equal number of tamping or packing-bars,

1). Thelower ends of these bars are provided 7 5 with laterallyprojecting feet or cross-heads,

, which move up and down between the core F and shell K. This construction of the ends of the tamping-bars presentsI a greater surface for packing the tile material, and also pre- 8o vents it from falling through onto.the table' The intermediate portions of these bars pass through the notches t in the guide o, which causes them to always move in their proper places.

Secured to the crosspieces b b, by means of suitable bearings,is a vertical shaft, H, to the upper end of which is secured the gear-wheel t, and upon the lower end is movably secured, by means of a feather, the gear-wheel u. The 9o wheel t engages with an annular cog-wheel, o, around the hopper J, and the wheel u with cogs w around the periphery of the table I. These two gear-wheels cause the hopper and shell to revolve in unison, while-the core-pro- 95 tector can be caused to revolve with them or in the opposite direction by means of a casting, W, secured to its top. The upper edge of this casting is provided with teeth X, which can be made inclined in either direction as roo are kept more cleanly, and the concrete is kept from adhering to the hopper or protector,and'

the tile has a smoother and better surface when completed.

Secured to the rear partof the machine, by means of the hangers e, is a counter-shaft, B, upon which are placed three pulleys, f, g, and h. Power which is applied to this countershaft through the belting fe' is transmitted through the belting j to main shaft c, upon which are placed the face-pulleys r wk, and also the sprocket-pulley l. From the shaft 0 power is transmitted to the levers O through the pulley y on the shaft-or stud L, the eccentrics M, which are connected with the pulley y by a suitable train of gearing, and through the rods N, one end of `each of which is connected'with one of the eccentrics M on the shaft d', and the other end with the vend of one of the levers O. Power is also transmitted from the shaft c to the hopper J and table I through the pulley Nn and gear-wheels s s; or an intermediate shaft, G, can be used and one of the gears s be secured to the end of it. As it is desired to move the rack-bar E either up or down, power is applied to it through the reversing mechanism, consisting of two intermeshing pinions, z and n, which are secured upon the lower end of a lever, Z. The lower one of these pinions,z,is operated by means of the sprocket-pinion m,which is connected with the sprocket-wheel Z on the shaft c by means of the chain i. Ashaft, D, is journaled to the cross-pieces a a, and is provided with a spurwheel or pinion, p, at one end, which engages with the rack E, and with a cog-wheel, o, at the other. The lever Z is pivotally secured to one of the cross-pieces a in such a position that by moving its upper end by means of the rack-bar lever e the pinions z and n can be made to alternately engage with the 'cog-wheel o, or be thrown out of engagement with it entirely. When it isv desired to move the rackbar E in one direction, the gear n is made to engage with the wheel o, as shown in Fig. 1, but when it is desired to move it in the other direction, the gear z is made to engage with it, and the gear n runs idly upon its bearing. The lever e is retained in either position by means of a notch which engages with the staple 1. v l As the tile is formed by the accumulation of concrete or other material between the hopper and core protector, or between the shell and core, rather, the table R is gradually forced downward, carrying with it the shell K around the core F. A lever, T, is secured at one end to the under side of the journal-box U, and at its outer end is provided with a hand-hold,by means of which the operator can start the table R and shell K downward when the tile is first started. After the tile has been formed, the core, F is withdrawn from the interior by causing one ofthe gears z or n to engage with the cog-wheelo. The shell K, with the inclosed tile, is then removed from the table, andan empty shell put in its place. The lever Z is then shifted so as to throw that gear out of engagement with the wheel o and the other gear in. This causes the rack-bar E to move in the opposite direction, and to take the table up with it into its first position,when thesame process is again repeated. The tile is easily removed from the shell K by inverting the shell and letting the tile fall the distance that the shell is longer than the tile, which will so.

loosen it that the shell can then be removed by lifting it upward, and letting the tile remain in its place to dry.

To facilitate the removal .of the core F from the interior of the tile, it is made contract-ible, and consists of a sheet of metal having its edges united at one side in a butt-split joint,:r. Secured upon the inner sides of this core are two ribs, y y', one of which is at the joint m' and the other is directly opposite. end of one of these ribs is an offset or loop, within which are secured the rings g gr.v Secured to the opposite sides of these rings is a rod, h', which keeps them at the same distance apart, and causes them both to operate together in expanding or contracting the outer shell. To the lower ring and to the lower end of the core a coiled spring is secured, which also assists in contracting the core. The core is secured to the top of the rod St by means of a short arm,which connects it with the top ring. When the rod St is forced upward,it causes the movable sides of the rings to press against the rib at that side and forces it outward,thus expanding the core, while if the rod is drawn downward it withdraws that side 0f the rings from the rib and causes the core to collapse. The upper end of this core is made slightly tapering, so as to more readily enter the lower end of the core-protector, and thus prevent the escape of concreteat that point.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1.
